First off, these are meant to be played, not read. I get it, really. It always seems off that reviews are in for a product that just came out, in this case pretty much 24 hours ago!
These encounters are short with the exception of a 3 part sequence, which could easily take a full session or longer.
The 12 have a good mix of combat and RP episodes, and there are a few keepers here for sure. A few really jumped out at me and I'll be using them to kick off my Eberron campaign.
The Callestan Clash is a great little insert, ideal for groups that are into RP. It's very different than your usual dungeon bash fare, and could set the PCs up with allies or enemies later depending on how it turns out.
Double Immiscibility is a real gem, and has an flavorful combat in an unusual location and even RP potential leading up to the big fight.
The Fallen Mad is the 3 parter, and and should satisfy combat loving players. For only 7 pages total, it seemed odd and a waste of space to recap parts 1 & 2 in the intros of 2 and 3. Additional content would have been preferable!
Not bad value for the money, and at the very least will give you plenty of ideas to kickstart your game.
I trust longer adventures are coming soon!
